View source for Raspberry Camera API

Back to [[Robobot]]

===Raspicam===

To be used from C++ direct or through openCV.

A rather short raspberry pi camera API is available from https://www.uco.es/investiga/grupos/ava/node/40.
And can be downloaded from https://sourceforge.net/projects/raspicam/files/, 

or get the file from sourceforge with no GUI, with:

 cd ~/Downloads
 wget --no-check-certificate -O raspicam-0.1.9.zip https://downloads.sourceforge.net/project/raspicam/raspicam-0.1.9.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fraspicam%2F%3Fsource%3Dtyp_redirect&ts=1486483484&use_mirror=netix

Once fetched and available on the raspberry, then
Unpack and install:
 unzip raspicam-0.1.9.zip
 cd raspicam-0.1.9
 mkdir build
 cd build
 cmake ..
 make
 sudo make install
 sudo ldconfig

The library is installed in /usr/local, and therefore to make cmake find it the path needs to be added to startup configuration, in file ~/.bashrc 

 nano ~/.bashrc
 add at the end:
 export CMAKE_PREFIX_PATH=/usr/local/lib
 source ~/.bashrc   # to implement export

Test with
 raspicam_cv_test
That takes 100 images and saves 3.
